Well, it is a long time I've been asking myself the same question. Indeed, a chilean told me some time ago that this is exactly hat happens to Mapudungun (Mapuche language). If you spoke it, you were seen like an intruder. Unfortunately, I could not verify this statement in the web so far, only maybe some clues in that strange 'Microsoft lawsuit' in Wikipedia.
Can anyone verify that? It is a very interesting concept, and it makes a lot of sense.
